• Performing a fuzzy search may retrieve terms with similar spellings: ((sich OR (ficho OR (ischo OR (icho OR (isscho OR isich))))) OR sch)~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((sich OR (ficho OR (ischo OR (icho OR (isscho OR isich))))) OR sch)".
• Adding a wildcard symbol may retrieve word variants: ((sich OR (ficho OR (ischo OR (icho OR (isscho OR isich))))) OR sch)*.
